Hola Celso,

You can reproduce the same on the UNIX shell with:

$ printf "\n%-10s Fim\n%-10s Fim\n" "Variável" "Variavel"

Variável  Fim
Variavel   Fim


$ printf "\n%-10s Fim\n%-10s Fim\n" "VariXvel" "Variavel"

VariXvel   Fim
Variavel   Fim

The second test (changing the accented char 'á' by 'X'), shows that the
problem/bug is a) more generic, not only in PostgreSQL and b) has todo
with being the UTF-8 char 'á' a two byte char, while 'X' is only one
byte.

I have no solution, though at the moment...

Obrigado
